Frames that are smaller than the minimum Ethernet frame size of 64 bytes are referred to as 'runts.' These frames are usually the result of collisions or other errors in the network. Understanding what runts are helps diagnose issues related to collisions or damaged frames in a network. Frames larger than the maximum Ethernet frame size (typically 1518 bytes, or 1522 bytes for VLAN tagging) are referred to as 'giants,' and 'jabber' describes a condition where a device is transmitting frames longer than the allowed maximum, often due to a malfunction. A 'collision fragment' refers to the remnants of frames that were involved in a collision on a network using a CSMA/CD protocol, which is a different concept.
